About hc-3

Information about the hc-3 data set.

Summary.

The data set contains recordings made from multiple hippocampal areas in Long-Evans rats, including: Cornu Ammonis: CA1 and CA3; dentate gyrus (DG), and entorhinal cortex: EC2, EC3, EC4, EC5. The data was obtained during 442 recording sessions and includes responses of 7,737 neurons in eleven animals while they performed one of fourteen behaviors. Total time for all experiments is 204.5 hours. The raw (broadband) data was recorded at 20KHz, simultaneously from 31
to 127 channels. The raw data was processed to extract the LFPs (Local
Field Potentials) and detect spikes. Included in the data set are the following items:

Times and waveforms of detected potential spikes.

Results of spike sorting.

LFPs.

For many sessions, the coordinate and direction of the rats head and video files from which the positions were extracted.

Metadata tables giving properties of the neurons and characteristics of the recording sessions.

Format of the data.

The format of the data is described in
crcns-hc3-data-description.pdf. The data for each session is stored in a tar.gz file. The total size of the data is about 433 GB compressed. Not all of the data needs to be downloaded to use the data set. Document crcns-hc3-data-description.pdf gives an overview of the data set and describes how to identify sessions of interest. File crcns-hc3-session-cell-counts.zip contains lists that specify the number of cells from each region for each session and also lists which sessions have the most number of cells from each region.
